I found the thread, it is an 8500 board in a desktop case. The thread is "Odd Power Macintosh 7xxx? Setup" from hyperneogeo. The CPU is an overclocked 604ev, not 604e. I should have gone looking first before blabbing. But that raises a couple of questions. 1. Can the 8500 actually run an ev, or...

With regards to the 604e running on the 85/9500, I can't really say. I believe there is a thread on the board that shows a crossover 8500 prototype running a 604e. It could be a revision change, as they went forward into the next model line, to test out CPU hardware. That board may or may not be...

I remembered something about the powerwave that I read on LEM. I had been looking for info as I own four power computing computers, powercenter, power tower pro, power tower, and I think another power center. Three g3/g4 upgrades, and one has a 210 604e in it. Anyways, the powerwave is a 604...

I forgot to add some more info on the s900. it could pertain to the power clone machines as well. There was a card population issue. This cars in slot one, that one in slot two, etc. Sometimes the cards would be recognized and run fine, other times the operator had to move the cards around...

Do you have another PCI mac to test the rage 128 on? Aside from the test showing a possible issue on the board, from what you have written, the machine works with the original card, but goes toes up with the rage. It seems likely that it may be that the card is bad, or it is not a mac card...

Have you tried placing the video card in a different slot? There may be an issue with the newer card running in that slot. I ask as I am reminded of posts on another site regarding the design of the Umax SuperMac 900 models regarding card placement being an issue. Some folk had issues with card...

If there are no attachment holes for a heat sink, that means it had a plastic frame that had two edges on it that slide under the edge of the cpu. The plastic frame has a centrally located, threaded hole in its center that sits over the chip die. An appropriately designed aluminum heat sink...

I was thinking about your issue with getting your emac to boot up and a dim recollection of my own emac came to the fore. The keyboard could have an issue. I had a problem with my unit not booting when I first got it. As it had no keyboard with it, I picked up a used,untested emac keyboard. I...

Well, non-bulged caps is a good sign. You may not have to do anything there. I just checked and found these two apple discussion web pages that may help with your reluctant Macs. https://discussions.apple.com/thread/518038 https://discussions.apple.com/thread/1147126 both links will give...

It seems to me that I have read of some of the earlier eMacs, 700, 800, and 1ghz models had issues with the capacitors going bad on some units. This could be a. factor. Also, you may wish to remove one stick of ram and try to start it then. And from frequently ghosting over other topics on...

When PowerPC was outlawed, only outlaws had PowerPC. I am a PowerPC outlaw.

Just a quick question. Do the machines have ram? Depending on the model, you can run up to 2gb in it, unofficially. No memory installed may give you the dead machine treatment. I have not tried to start mine without ram, so I dont know what exactly would happen.

I had that issue with my 1.42ghz eMac. I had not turned it on for three months, and when I needed to use it, no joy. After removing the plate covering the memory, and inspecting the caps that are visible there for damage, I turned to replacing the battery. My machine booted right up.The battery...
